Yeah it can be done, im running it now. I would make your vista partition bigger tho.

A word of thought. I have a 40gig hdd 30gig win xp c/drive and a 10gig partition of xp as a back up d/drive, I have installed vista ultimate 3 times now on my c drive but the only problem i find is that the built in back up in vista tends to reduce my drive by nearly half IE to about 15g. I have never found away to delete or switch of the back up, so it was really pointless me upgrading as i would fill 15gig easy and it would start to slow my computer down. you are putting a different version on that doesn't have the back up( I think) so you might get away with it but in all honesty i would buy a bigger hdd first before going down that option.
